DHCLIENT can't get lease via WLAN

Hello,

I have a new laptop running Fedora Core 2. It has a wireless NIC which
uses the native Prism54g driver.

Connecting to my home router via a LAN connection works fine using
DHCP, but even after several weeks of tinkering I still can't get a
connection via WLAN. As far as I can tell, the problem seems to be
that dhclient can't get a lease over a wireless connection. If I run
"dhclient eth1" in a terminal window, I get the following output:

Listening on LPF/eth1/00:91:4b:68:f2:90
Sending on LPF/eth1/00:91:4b:68:f2:90
Sending on Socket/fallback
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 7
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 7
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 12
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 12
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 13
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 10
No DHCPOFFERS received.

Suggestions anyone?

No, just questions
- Is it working with a fixed IP address ?
- Do the router's security settings match your laptop configuration
(ESSID, encryption... ) ?
- Have you checked the output of iwconfig, iwlist, iwevents, iwspy,
iwwhatever ?

Hello,

I've got the same problem with FreeBSD (BSD Unix) I think it is because
that Wireless connections require that the card be "associated" with a
particular access point thru its SSID. On my system the SSID is
"linksys" because that is the default that Linksys equipment is set to.
The problem is you have to tell dhclient to use it. I have not been able
to figure out how to do that yet. I've gotten around this problem by
manually configuring the card like this: "ifconfig an0 inet
192.168.1.200 netmask 255.255.255.0 ssid linksys up". You will have to
set up resolv.conf and your defaultrouter manually of course.

Good Luck,

Dave
